Our series of NASCAR driver interviews continues this week with Greg Biffle, who is currently 11th in the Sprint Cup Series point standings for Roush Fenway Racing.

Q: When you're on a long green-flag run and not racing around anyone, what do you think about?

A: You're in the moment, so what you're constantly thinking about is being efficient with your tires and trying to run the fastest lap you can. You don't want the guy behind you catching you and you don't want the guy in front of you to get away.

I think there's this perception in the sport and with fans that when they see a long green-flag run and the cars get strung out, they think we're not racing as hard because we're not close together. But we're still trying to catch whoever it is in front of us, and we're still running as hard as we can to close in on them.

So what I'm actually thinking about is: "What adjustment do I need to make? What do I need to tell (the team)? How can I run a better lap?" And I can experiment a little bit, but I don't want to lose any time. I don't want to make a mistake and run two-tenths slower, because I just lost two-tenths to everyone.

Q: Fans often come up to you and want to discuss a moment or race from your career. Which one comes up the most?

A: Well, a non-racing moment that a lot of fans bring up is the Subway commercial (where Biffle uses sandwiches to illustrate a crash to former crew chief Doug Richert). A lot of people talked about that, although that's sort of died off a little bit.

It changes with time though. My first win in Daytona in 2003, then the 1000th win (for Ford) last year at Michigan — people talked a lot about that. They'll bring tickets to get signed. But it's usually the last big moment.

Q: If someone paid you $5 million to design a new racetrack and gave you an unlimited budget, what kind of track would you build?

A: I would build a 1-mile to 1.25-mile racetrack. We've got a lot of 1.5-mile tracks and we don't have as many 1-mile tracks. I think it can be in between Richmond size (0.75-mile) and Charlotte (1.5 miles) and have a happy medium with progressive banking.

I'd be a tiny bit more aggressive with the progressive banking, but the shape of the track is really important when it comes to that. You take Darlington, for example — it doesn't have progressive banking, but we run around the top just because of the way it's shaped. Your corner entry is really square and really sharp on exit, so you have drive it like that.

So it has to be laid out properly and then have the proper amount of banking so you match the speeds from up at the fence and down at the white line. That would be the perfect racetrack in my eyes.

Q: If you had a day off to do anything in the world you wanted — but you were not allowed to race — what would you do?

A: I'd like to see some sand dunes from other countries like Dubai. Get all my equipment — my sand cars, my UTVs, all that stuff — and go be able to do some of that recreationally. I really enjoy off-road and sand dunes and all that, but I don't ever really get to go to any dunefests or sandfests or any of those things because they're all on the weekends.

I'd love to run some off-road races, too, I think they'd be fun to do — like the Mint 400 — but they're all during our season.

Q: You get to have a lot of cool experiences away from racing through your job as a NASCAR driver. What's one that sticks out?

A: All the coolest things I've gotten to do were when I was sponsored by the National Guard. Probably flying in the Apache (helicopter) out in Utah, flying up the face of a snow-covered mountain, then nosing over and going over the other side of it. We did some maneuvers like "return to target," where you pull up and do a pedal turn, then aim back down at the target as if you had your guns pointed at it.

I got to shoot the 155 (mm) howitzer; I pulled the string. You've got this high-tech piece of equipment, and it's like a shoelace that you pull that fires it. (Laughs)

I also got to land on the flight deck of an aircraft carrier. So those are all really neat things.

Q: When you go home after a bad day at the track, do you vent to someone about it or just keep it to yourself?

A: I just keep it to myself until I get over it. I'll kind of moan and complain — I coulda done this, shoulda done that — but typically I get home and I see my daughter and my dogs and family, and it pretty much goes away.

You feel like, "OK, it might have been a bad day, but it probably wasn't as bad as some other people's." When you think you're having a bad day, just look around at other people's struggles. All of the sudden, yours aren't as much of an issue.

Q: If you could point to another driver as a good example for your daughter or other children in the garage, who would it be?

A: I would say both Matt (Kenseth) and Jamie (McMurray). But I'm around them a lot, so it's hard to rate them over other guys, but I see that they really care about their families and do lots of things together. They're good role models.

Q: When you stand around with other drivers and tell old racing stories, what's one of your favorites to tell either about something that happened to yourself or someone else?

It was just a bad accident, a really huge wreck. The car went in at 207 mph. The data showed it was more severe than wrecks other people have probably not survived. I've still got the car. It doesn't look very good.

Q: What's a TV show you're really into right now?

A: Unfortunately, I have to watch The Bachelor and The Bachelorette when they're on, because there's give and take on the TV shows (with wife Nicole), right? But I also watch The Voice and Modern Family and some of the sitcoms that are really entertaining.

Q: What's the last movie you saw, and was it any good?

A: I hadn't watched a movie in probably a year, but I watched We're The Millers on my way to Utah to do a road course test about two weeks ago. I was laughing hysterically on the plane on the way there, and it was the funniest thing I've seen in a long time.

It's inspired me to watch more movies when I get a chance, which is typically just airplane rides. The rest of the time, we have appearances and family and hobbies and activities, so I'm going to have to create a movie night or something.

But I'm the guy who when you start the movie, after 30 minutes I'm snoring. No matter how good it is, I can't stay awake. That's one of my bad traits.

Q: If you could give a piece of advice to your younger self — something you know now that you didn't know then — what would it be?

A: I think we all look back and critique decisions we've made, but I'm pretty happy with the choices I've made. You just wish you knew about technology in racing, right? (Laughs) If I could go back two years ago and know what I know today, it'd be crazy.

Like when I won a lot of races in '05, we figured out how to get the car attitude right and all that. But you just wish every year you were a year ahead of your competition on figuring out the mousetrap.

I guess no matter who you are — not just professional athletes — there's always that balance between saving money and enjoying the little bit of off time you have. People planning for their future is one thing, and then you always go back and say, "Oh, I probably didn't need that (purchase). If I would have saved that money 10 years ago, I'd have a lot more now.'

As far as racing, you start thinking back — the championship in '05 you missed, well now with the points system they give bonus points for (regular season) wins. Well gosh, I would have won the championship! I won six races. Then Homestead — now it's if you're in the top four and you win the race. Well, I would have won two championships now. So every time they change it, it gets better for me. It's like, can we make this retroactive? (Laughs)

Q: I've been asking each person to give me a question for the next interview. Last week was Austin Dillon and he wanted to know: If you could have any crew chief from the past — nobody who is in the garage now — what crew chief would you want to have?

A: Man, that's really hard. You know, the first one who comes to mind is Dale Inman. They won a lot of races (at Petty Enterprises). But also Larry McReynolds, Andy Petree — I drove some races for him. And I always thought Fatback (McSwain) was pretty smart in his time. He won a lot of races, too.

Q: And do you have a question for the next person?

A: I guess it would be: "If you had the chance to drive any car in the garage area other than your own, which car would it be and why?" And don't make it Jimmie Johnson, because that's too easy.
